Today, at 8 a.m. ET, a panel of world climate leaders, among them former U.N. Secretary General Kofi Annan and journalist Thomas Friedman, will gather in Copenhagen and answer the top questions that you submitted to the CNN/YouTube Climate Debate channel.

You can watch them address the issues that matter to you in real-time: We'll be live-streaming the debate at www.youtube.com/cop15.

Thank you for making this event truly international. We received thousands of questions from Italy to Brazil, Nigeria to New Zealand. To get a scope of just how many countries are represented, see this map, which depicts global submissions through a Google Earth layer.

And if you didn't have a chance to submit a question, but still want to raise your voice about climate change, we encourage you to join the discussion on Twitter during the debate using hashtag #cnnytdebate.
